Objective To investigate the effects of ionic strength on kinetic parameters of hybridization with piezoelectric gene sensor arrays. Methods A gene sensor array of 2×5 was made with gene probes of drug resistant genes from Staphylococcus aureaus immobilized on gold coated surfaces . The complementary sequences of these genes were hybridized on the gene sensor in 5 kinds of Tris HCl buffer solutions containing NaCl at different concentrations. The data of sensor frequency were collected and the kinetic parameters analyzed with computer. The hybridization time and frequency changes were compared at different NaCl concentrations. Results With the increase of NaCl concentration, binding rate constant, association constant, maximum binding amount and the frequency differences between before and after hybridization were all increased, but dissociation constant was decreased. Meanwhile, the range of frequency fluctuation was extended and the time for hybridization prolonged along with the increase of NaCl concentration. Conclusion Proper ionic strength is beneficial for gene hybridization, but high ionic strength is harmful to the oscillation of piezoelectric crystal.
